I-HPMC, okanye i-hydroxypropyl methylcelceluplose, yi-polymer eqinileyo yamanzi asetyenziswa ngokubanzi kwi-cosmetics, ukutya, amayeza kunye namashishini amayeza kunye namashishini anqabileyo. Kwimigangatho yotywina yolwelo, i-HPMC inoluhlu olubanzi lwemisebenzi.
1. Ukuthamba
Enye yezona zinto zibalulekileyo ze-HPMC injenge-thi checker. Izicoci ezingamanzi zihlala zifuna ukuba ne-viscofity efanelekileyo yokuqinisekisa ukuba lula ukusetyenziswa kunye neziphumo ezilungileyo. I-viscofity iphantsi kakhulu inokubangela ukuba isithintelo sibe ngamanzi kakhulu kwaye kunzima ukulawula ngexesha lokusetyenziswa; Ngelixa iphezulu kakhulu i-viscofity inokuchaphazela ukusasazeka kunye nokususwa kwemveliso.
I-HPMC inokugcina i-viscofity ephakathi yeendlela ezingamanzi ngokwenza ubume benethiwekhi ye-collofal yamanzi. Ukubizwa kwayo emanzini kunye ne-viscoelity I-LILCOOECK I-LILY iyenza ukuba ikwazi ukunceda ukulungisa izinto eziqinileyo kulwelo kubushushu obahlukeneyo ngaphandle kokuchaphazela iipropathi zayo. Esi siphumo sokuqaqamba asikuphelanga nje ukuphucula iimvakalelo kwaye sisebenzise amava esibambiso, kodwa ukwandisa ukuzinza kwesicoci, ukuvumela ezinye izithako kwifomula (ezinje nge-surfacants zisasazeke kakhulu kulwelo.
I-2. Ukumiswa kwesitayile
Kwizicoci ezingamanzi, izithako ezininzi (ezinjengebliki, i-enzymes, i-enzymes, i-abrasmes okanye ezinye izithako ezisebenzayo) zinokuhlala ngenxa yomahluko wobushushu. Njengomntu onqunyanyisiweyo, i-HPMC inokuthintela ngokufanelekileyo i-sediment yamasuntswana aqinileyo okanye i-incollows, ngaloo ndlela i-insuble, ngaloo ndlela iqinisekisa ukuba izithako zesicoci zisasazwa ngokugcinwa nokusetyenziswa. Oku kubaluleke kakhulu ngenxa yokucofu equkethe iinkcukacha, iblezy okanye i-enzymes, kuba umsebenzi okanye ukusebenza kwezi zithako kunokwehlisa ixesha, kwaye i-sediment iya kuthi ichaphazele isiphumo sokucoca kwemveliso.
Isisombululo se-HPMC sineempawu zokuhamba ze-pseudoplastic, oko kukuthi, iveza i-viscofity ephezulu kumaxabiso asezantsi, ngelixa i-viscosity inciphisa ibhotile ye-Sheart , kodwa kulula ukuhamba xa kusetyenziswa.
3. Ukwenza ifilimu kunye neziphumo zokukhusela
I-HPMC inepropathi efanelekileyo yefilimu, eyenza ukuba ibe yifilimu yokukhusela kumphezulu weempahla okanye izinto ngexesha lenkqubo yokuhlamba. Le filimu inokudlala indima eliqela: Okokuqala, inokukhusela iintsinga zempahla ukusuka kunxibe ngendlela yokuhlamba ngexesha lokuhlamba; Okwesibini, emva kokuqulunqwa kwefilimu, kuyanceda ukugcina ixesha lokunxibelelana phakathi kwezithako ezisebenzayo kwi-stregent kunye namabala, ayaphucula ukusebenza kakuhle. Kwimigangatho ekhethekileyo yokuthintela i-conjition, efana ne-sutotendiners okanye iiarhente ezinamafutha asetyenziselwa ukukhusela amalaphu, iipropathi zokwenza ifilimu ze-HPMC zinokwandisa ukusebenza kwezi mveliso, ukwenza iimpahla zithambekele.
I-4. Ukulawula iipropathi zeJuam
Ukuzukulwana kwe-Foam nolawulo yenye yezona zinto ziphambili kulwakhiwo lokuqulunqa. I-HPMC ingadlala indima kummiselo we-foam kwizicotho. Nangona i-HPMC ngokwayo ayivelisi i-foam, inokuchaphazela ngokungathanga ngqo isizukulwana kunye nokuzinza kwe-foam ngokuhlengahlengisa iipropathi ze-ROIOOICRTER kunye nomoya wenkqubo. Kwezinye izicelo ezifuna i-foam engaphantsi (ezinjengeesicoci ezihlazo ezizenzekelayo), ukusetyenziswa kwe-HPMC kunganceda ukulawula ukuphakama kwe-foam kwaye kuqinisekiswe ukusebenza kakuhle koomatshini. Ukuze isebenzele i-foam etyebileyo, i-HPMC inokukunceda uzinzise i-foam kwaye wandise ixesha lako.
5. Ukuphucula uzinzo lwemveliso kunye nobomi beshelfu
Izicoci ezingamanzi zinokuba nezithako ezahlukeneyo ezisebenzayo, ezinje nge-enzymes, i-oxidants okanye i-Iniles, ebonisa imiceli mngeni kuzinzo lolawulo. Ubukho be-HPMC bunokuphucula ngokufanelekileyo ukusasazwa kwezi zithako zingazinzanga kwaye ubathintele ekutshintsheni nasekutshintsheni kwimichiza ngokuhlengahlengisa i-viscofity, ukunqunyanyiswa kunye neepropathi ze-RIOOOLOPREPE. Ukongeza, i-HPMC inokucothisa ireyitha yezithako ezithile ezisebenzayo kwifomula ukuya kuthi ga kwinqanaba elithile, ngaloo ndlela kwadlulisa ubomi bemveliso yemveliso. Oku kubaluleke kakhulu kwimichiza equkethe izithako eziphakamileyo zokulinganisa, ezinokuqinisekisa ukuba imveliso igcina ubuchule bayo obuyikhile kuyo yonke ishelufa yobomi.
I-6. Ukukhusela kwendalo kunye ne-biodegradiance
I-HPMC yindawo ethathiweyo evela kwi-seluplose yendalo kunye nokukhusela kwendalo. Xa kuthelekiswa nezinye ii-sheckenes zekhefu okanye ii-stabilizers, i-HPMC inokuchithwa yintsholongwane kwindawo ebonakalayo, ngaloo ndlela kuncitshiswa ifuthe kwindalo esingqongileyo. Ngokuphuculwa kolwazi lokuqonda okusingqongileyo kunye nokuqwalaselwa kophuhliso oluzinzileyo, abavelisi abangaphezulu nangaphezulu sele beqalisile ukukhetha izinto eziluhlaza eziluhlaza ezifana ne-HPMC ukunciphisa i-HPMC ye-Ofisi yeNdawo.
7. Lungisa ubume kwaye usebenzise amava okuzimisela
Iziphumo ezihlekisayo ze-HPMC azichaphazeli nje ukubonwa kwemveliso, kodwa nazo ziphucula kakhulu amava okusebenzisa izicoci ezingamanzi. Ngokwenza i-fluidoty kunye nokuziva ngathi isicoci, i-HPMC yenza ukuba imveliso ikhululekile kwaye kulula ukuyisebenzisa. Ingakumbi kwiifomu zokuphelisa eziphezulu, ukusetyenziswa kwe-HPMC kungazisa ukwenziwa kwe-HPMC kunye nokuthambisa okungakumbi, ngaloo ndlela kuphucule ulwaneliseko lwabathengi. Ukongeza, ukubenzela amanzi i-HPMC kwenza ukuba kube lula ukukrokrela emva kokusebenzisa ngaphandle kokushiya intsalela kwimpahla yokunxiba okanye kumphezulu.
I-HPMC isetyenziswa ngokubanzi kwizicwangciso zamanzi, ukudibanisa imisebenzi emininzi enjengamanzi amakhulu, ukumiswa kwezinto ezinqunyanyisiweyo, iifilimu zefilimu, kunye nemisitho yamabi. Ayinakuphuculanga uzinzo kunye nokusebenza kwezityholo, kodwa nazo zihlangabezane neemfuno zabathengi bale mihla kwiimveliso ezizinzileyo ngokusikhusela nakwiibhadicadiance. Kuphuhliso lwexesha elizayo lokwenziwa kweendlela zokucoca, i-HPMC iya kuqhubeka nokuba yinto ebalulekileyo yokunceda ekuncedeni abavelisi benza umsebenzi wemveliso kwaye baphendule kwimfuno yentengiso.
